Each crate, cage or barrel takes up 20 units of encumbrance in your +inventory or in the cargo hold of your starship. The NPC merchants buy and sell based on their planetary currencies, so you'll need to refer to +einfo banking for information about converting the values and determining the most profitable routes.

NOTE: More worlds and trade goods *will* be added in time. This is just to get the trade system up and running so we can see how it works. The merchant NPCs are located in the vicinity of major spaceports on these planets. Enjoy!
